Lithium metaborate (LiBO2) is a chemical compound.

Uses[edit]

Lithium metaborate or lithium tetraborate (Li2B4O7), or a mixture of both, can be used in borate fusion sample preparation of various samples for analysis by XRF, AAS, ICP-OES, ICP-AES and ICP-MS.

Lithium metaborate, lithium teraborate and lithium bromide mix fusion flux

Simultaneous determination of parts-per-million level Cr, As, Cd and Pb, and major elements in low level contaminated soils using borate fusion and energy dispersive X-ray fluorescence spectrometry with polarized excitation.[2]
